The presence of mana plants helps stave of Mana Deprivation, so they are grown commercially and considered very valuable by Fae.

Mana plants were speculated to have some form of symbiotic relationship with mana rats, since a group of mana rats became agitated and attacked the Tei'kaliath who attempted to remove a wild mana plant. This was confirmed when it was discovered that domesticated fields of mana plants that had mana rats tended to be healthier and grow faster than fields that didn't. Why this is so is still unclear.
